I’m curious how they differ in your opinion. Can you elaborate?
For context, I’m a Product Manager and it wouldn’t occur to me that either takes more bandwidth. However, I do think “bandwidth” carries a connotation of priority. “I don’t have the time to work on that P1” would be a rather shocking statement to hear, since a P1 should, by definition, be the top priority. “I don’t have the bandwidth to work on that P1” says to me that there’s something equally or more important taking that person’s focus.
